“…Also, the PCTFE polymers presently marketed by Honeywell, under the Aclar ® trademark, have remarkable gas‐barrier properties . As with ethylene (Halar ® from Solvay), propylene, isobutylene, but in contrast to vinyl acetate, [1‐(fluoromethyl)vinyl]benzene, which had led to statistic copolymers of low CTFE content (compared to that of the feed), CTFE can copolymerize with vinyl ethers to form alternating copolymers . A lack of comonomers of CTFE that behave as a less reactive monomer than this fluoroalkene exists, and it is worth finding some.…”

Methallylic monomers bearing triethyl or 4-diazabicyclo[2.2.2]octane (DABCO) ammonium side-groups are prepared and copolymerized with chlorotrifluoroethylene (CTFE). First, three different monomers are synthesized from chloro-2-methylprop-1-ene or 3-chloro-2-chloromethylprop-1-ene in fair to good yields (57-95%). Then, several parameters (initiators, aqueous or solution processes, temperature) of the radical copolymerization of these monomers with chlorotrifluoroethylene are investigated. Various initiators are tested in the presence of ammonium perfluorooctanoate (APFO) as watersoluble surfactant, and tert-butyl peroxypivalate/APFO leads to the best results in a mixed solvent (H 2 O/CH 3 CN/C 4 F 5 H 5 ). In all experiments, the radical copolymerization shows that CTFE is more reactive than the methallylic monomer as evidenced by the characterization of poly(CTFE-co-M) copolymer by nuclear magnetic resonance spectroscopy and elemental analysis. Thermal degradation of these copolymers by thermogravimetric analyses indicates that the copolymers are stable up to 180 C without any degradation and have a T d,10% above 300 C. Finally, their ionic exchange capacities range between 0.94 and 1.69 meq g 21 .

“…Although DABCO has two amine functions, various authors claimed that stoichiometry between chlorine atoms and DABCO does not allow to crosslink the polymer at low temperature. However, if the amount of DABCO is higher than that of the chlorinated sites, crosslinking may occur …”

“…PCTFE is only soluble in 2,5‐dichloro‐trifluoromethyl benzene at 150 °C), and (iii) the inherent difficulties encountered when cross‐linking. To overcome the aforementioned limitations, CTFE has been extensively copolymerized with monomers such as vinyl ethers (more than 300 patents have been deposited by Asahi Glass Co.), ethylene (poly(CTFE‐ alt ‐E), ECTFE, Halar ® commercially available by Solvay Specialty Polymers), and propylene (poly(CTFE‐ alt ‐P)) . In these three cases, the resulting copolymers are alternating in contrast to those based on vinylidene chloride, vinyl chloride, styrene, MMA, N ‐vinyl pyrrolidone, vinyl acetate, vinyl triethoxysilane, diallyldimethylammonium chloride (DADMAC), or fluorinated dioxolane that lead to random copolymers with low CTFE contents.…”

The radical copolymerization of chlorotrifluoroethylene (CTFE) with 3,3,4,4‐tetrafluoro‐4‐bromobut‐1‐ene (BTFB) initiated by tert‐butylperoxypivalate is presented. The microstructures of the obtained copolymers are determined by means of NMR spectroscopies and elemental analysis and show that random copolymers were obtained. A wide range of poly(CTFE‐co‐BTFB) copolymers is synthesized, containing from 17 to 89 mol % of CTFE. In all the cases, CTFE is the less reactive of both comonomers. Td10% values, ranging from 163 up to 359 °C, are dependent on the BTFB content. These variations of thermal property are attributed to the increase in the number of C‐H and C‐Br bonds breakdown when the BTFB molar percentage in the copolymer is higher. Tg values range from 19 to 39 °C and a decreasing trend is observed when increasing the amount of BTFB in the copolymer. This observation arises from the higher flexibility of the copolymer when increasing the number of fluorobrominated lateral chains. These original fluoropolymers bearing reactive pendant bromo groups are suitable candidates for various applications. © 2014 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.

“…This has been accomplished by adding hydrocarbon acrylic polymers and fluorine-containing compounds. 4 Fluorine-based materials are extensively used in surface protection due to the properties they can impart, such as water and oil repellence, weatherability, chemical resistance, stain repellence, and durability. 1 Organic fluoropolymers have been used in many fields due to their special properties that no other polymers can provide.…”

Latex paints are often preferred over solvent-based paints due to their good gloss and color retention, ease of handling, and lower volatile organic contents. However, matt latex paints tend to show poor stain resistance since they develop highly porous and rough surfaces. In recent years, matt latex paints have been improved in their stain resistance with resulting better cleanability, by adding hydrocarbon acrylic polymers and fluorine-containing compounds. In this work, we prepared fluorinated acrylic emulsions of the copolymer of butyl acrylate (BA) and perfluorobutylethylene (PFBE), which were introduced in latex paint compositions. The properties of the modified paints were evaluated by performing stain resistance tests with several domestic products. It was observed that they had good stain release properties, thus conferring good properties to the final painting system. They contain the self-cleaning behavior typical of fluorinated coatings, which have been proven by the decrease of their surface energies. Since the cleaning procedures of a matt paint film can also impart some gloss increase, the wet and dry burnishes were also evaluated. The results have shown improvements in stain resistance and cleanability of the modified matt latex paints with the maintenance of their stability and the coatings gloss as required.
